Wiz formatter and linter

This repository contains the source-aware formatter and semantic linter for the Wiz language.

Published packages:

• @wiz-sh/formatter formats whole files and ranges, checks formatting, and produces deterministic minified output.
• @wiz-sh/linter runs correctness, safety, suspiciousness, and style rules with precise ranges and classified fixes.

Both packages consume the compiler’s lossless syntax and semantic APIs. They do not maintain a second parser or duplicate name resolution.

Guarantees

• Formatting is deterministic and idempotent.
• Quote style is preserved unless a rewrite is semantically proven safe.
• Heredocs, comments, arrays, redirections, expansions, typed declarations, and incomplete editor input remain structurally represented.
• Safe and unsafe fixes remain distinguishable.
• Minification preserves shell semantics and is tested separately from normal formatting.

API

import { formatSource, minifySource } from "@wiz-sh/formatter";
import { applyLintFixes, lintSourceFile } from "@wiz-sh/linter";

Development

bun install
bun run check
bun run build

Tests cover formatter idempotency, ranges, malformed input, every registered lint category, exact diagnostics, configuration overrides, and fix safety. CLI integration is owned by wiz-sh/wiz, while editor integration is owned by wiz-sh/lsp.
